The STM32F767 device has two audio-related features: Inter-IC Sound (I2S)
and the Serial Audio Interface (SAI) but that is the limit of my knowledge
at present. Download a copy of the STMicroelectronics RM0410 Reference
manual for more information.

A change of heart, not a change of mind ;-) No, we're still focused on
realtime embedded systems and are not contemplating any Linux-style support.
If we do eventually support a realtime OS on the Cortex-M systems (which is
becoming more feasible) then it would be based on our embedded version of
the Project Oberon OS.
